Hey,

So I have fitted this recirc valve. I'm assuming there is meant to be a hose attached to this big hose. But where is it meant to go? And where can I get the hose?

Most of the time it should be under the TMIC blanked off

So flip it over and then put a cap on it of some sort? Any idea on the best way to block it? And assuming it is safe to drive at the moment as it is just a blow off valve?

No sorry you should have a pipe but when people put a dump valve on it they block the other pipe off it's normally around or under the TMIC when people blank it off and tuck it out the way. 

Best way to show you would be this I guess with a fitting guide 

The pipe was blanked off just to the right of the intercooler. All on now and hopefully correct, engine sounded nice when running so hopefully everything working.

Cool :)
